Embodiment 1

[0042] Below, refer to Figure 1 to Figure 5 Example 1 of the present invention will be described.

[0043] image 3 This is a schematic structure of a front-loading washing machine (hereinafter referred to as a washing machine) 1 viewed from the right side. image 3 Among them, the washing machine 1 includes: a rectangular cylindrical frame body 2 forming an outer shell; a top cover (top cover) 3 with an operation panel (control panel) etc. (not shown) on the upper surface; 4 etc.

[0044] A cylindrical water tank 5 capable of storing water is horizontally provided in the frame body 2 . A drum 6 rotatable around its horizontal axis is accommodated in the water tank 5 . A plurality of (for example, two) hangers 7 are provided between the bottom plate 5 a of the water tank 5 and the end portion 4 a of the table 4 below the frame body 2 . Through these suspensions 7 , the water tank 5 is supported on the table 4 of the frame body 2 in a vibration-proof manner. The specific...

Embodiment 2

[0068] Next, refer to Figure 6 Example 2 of the present invention will be described. Parts that are the same as or similar to those in Embodiment 1 above are assigned the same symbols, and detailed description thereof will be omitted.

[0069] Wave washers 41 , 42 are provided on the suspension 40 of the second embodiment instead of the shells 18 , 19 . These wave washers 41, 42 are formed as doughnut-shaped discs. upper side ( Figure 6 The wave washer 41 on the middle and upper side) exerts a downward force on the upper bearing 13, and the lower side ( Figure 6 The wave washer 42 on the lower middle side) applies an upward biasing force to the lower bearing 14 . in addition, Figure 6 In , the cross-sections of the two wave washers 41 and 42 are shown in a flat state.

[0070] According to the second embodiment, in addition to the elastic force of the friction member 22, the elastic force of the wave washers 41 and 42 is added, so that the axial vibration of each com...

Abstract

To provide a drum-type washing machine where characteristic is stable, precise attenuation force according to amplitude is obtained without regard to a drum rotation frequency and shaking suppressionis also provided. In the inside of a cylinder 9, a pair of bearings 13 and 14 are fixed so as to be separated from each other, and cases 18 and 19 are arranged between the bearings 13 and 14. Then, ashaft 24 having a friction member 22 compressed in an axial direction is put through the bearings 13 and 14 via the cases 18 and 19. Thus, with relative reciprocation of the shaft 24 with respect tothe cylinder 9, the friction member 22 slides against the shaft 22 to obtain the attenuation force. In addition, due to the elastic repulsive force of the friction member 22, gaps between respective components put through the shaft 24 are eliminated, so that shaking in the axial direction is suppressed.

Description

(1) Technical field [0001] The present invention relates to a drum-type washing machine (drum-type washing machine) in which a water tank accommodating a drum is anti-vibrationally supported by a suspension. (2) Background technology [0002] The drum type washing machine is rotatably provided with a horizontal axis type drum for storing clothes in a water tank for storing washing water. The drum is supported by bearings through a shaft and driven to rotate by a motor. The water tank housing the drum is supported by a plurality of suspensions so that vibrations generated during washing, dehydrating, and drying processes are not transmitted to the casing of the washing machine (for example, refer to Patent Document 1). [0003] [Patent Document 1] Japanese Patent Laid-Open No. 9-187596 [0004] The suspension generally used in the drum type washing machine in the past is known as the first example Figure 7 The suspension 102 using an oil damper (oil damper) of the structur...
